REN EWABLE-SEAT VALVE.

SPECIFICATION forming part of Letters Patent No. 653,300, dated July 10, 1900. Application filed February 5, 1900; Serial No. 3,976. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDMUND H. LUNKEN, a citizen of the United States, residing at Den ver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Renewable-Seat Valves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class of valves among which may be enumerated globevalves, check-valves in the form of globevalves, angle-valves, and, in short, all that class of valves having an inlet-opening,a pipeopening, and an interposed valve-seat openin g, with a valve-seat covered by a valve that moves to and from its seat always in planes parallel with the plane of the seat; and it has for its object the provision of a removable and renewable seat for this class of valves which can be readily applied and removed without trouble or loss of time and without disconnecting the valve from its pipe-fittin gs, thereby greatly increasing the efficiency of the valve and prolonging its life.

It also has for its object the provision of a seat which will not only be removable and renewable, but also reversible.

The novelty will be hereinafter set forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure l is an axial side elevation of so much of a globevalve asis necessary to illustrate my invention in one form. Fig. 2 is a plan View of Fig. 1 with the cap or bonnet removed. Fig. 3 is an enlargedperspective of one of the seat-holders. Fig. 4 is a view corresponding to Fig. 1, showing a modification in the construction. Fig. 5 is an enlarged detail in section of part of the construction shown in Fig. 4.

The same letters of reference are used to indicate identical parts in all the figures.

In Figs. 1 and 2, which represent an ordinary globe-valve or so much thereof as is necessary to illustrate my invention, A represents the body, withopposite pipe-openings a Z; to form inlet and outlet openings for the valve. Within the body between these openings a l) is the usual ,diaphragi'n 0, having through itan opening (1, containing the valveseat D, with which the valve e (represented by dotted lines) engages and is moved to and from the valve-seat to close and open the valve by the usual or any suitable stem f, passing through and engaging with a cap or bonnet l3, screwed down to the neck O of the valve.

So far the construction described is that of any ordinary globe-valve, and I will now proceed to describe the application of my invention thereto.

Loosely fitted within the valve-opening in the diaphragm c is a removable ring-seat D, with an exterior rabbet or cut-out portion 9 onboth sides to fit the opening in the diaphragm and with upper and lower exterior beveled portions h to form the valve-seat,

with which the correspondingly-beveled lower portion of the valve 6 engages. It will thus be seen that the ring-seat is not only removable and renewable, but also should one side become worn and leak it can be reversed, thereby greatly prolonging the life of the valve. To hold this ring-seat securely to its place in the diaphragm c, I provide a holder, Fig. 3, composed of an upper ring 2', with two opposite pendent arms j and with outwardlyprojecting teats or lugs 7c, (in this instance shown on the outer sides of the ring i and in line with the arms j.) Any other location of these lugs, however, may be employed, and instead of there being two one only may be used. Thelugs 7o fit into recesses Z, Fig. 2, in the neck of the valve, so as to prevent the holder from turning when the bonnet or cap B of the valve is screwed down uponit, and the arms j are of such length that they pass down on each side of the passage-way of the valve without obstructing the same, and their lower ends, preferably beveled, engage and bear upon the top groove 9 of the ringseat to hold the same securely in place.

In Figs. 4 and 5 I have shown the ring 1101 .the holder provided with an inwardly-extend ing flange m, confined in a groove n in the plug of the cap or bonnet B, whose lower end is slightly spun outward to hold the same in place, thereby locking the ring of the holder to the cap or bonnet, so that it will be raised or lowered by the raising or lowering of the bonnet, as will be readily understood. This construction forms a swivel-joint betweenthe holder and the cap or bonnet, which enables the latter to be screwed up or down without turning the holder, which is held by its groove or grooves, as will be readily understood. It is also apparent that there is nothing in my present invention to prevent its advantageous use in valves in which the bonnet or cap is screwed upon the outside of the neck or shell, and it can also be advantageously used in valves whose bodies are made of iron and in which the cap or bonnet is bolted to the shell or casing in the usual or any suitable manner. Again, while the ring t', carrying the arms j, has been heretofore described as solid, yet, as seen in Figs. 2 and 3, it may be split or cut through on one side, as at p, to afford a slight clearance at that point and give the ring some elasticity by which it can be made to fit more perfectly in the neck of the valve, and by its elasticity and tendency to press outward it may be used without the retaining-lug to hold both itself and the arms which bear on the ring-seat from turning.

Having thus fully described my invention, I claim 1. In valve construction in which the valve moves to and from its seat in constantly-parallel planes, the combination of the body having inlet and outlet openings and an interposed seat-opening, a ring-seat fitted to said last-named opening, an arm on each side of the valve-passage bearing upon said ringseat, a ring connecting the upper ends of said arms and engaged by the cap of the valve, means for holding said ring and arms from turning, and the valve which engages with the ring-seat, substantially as described.

2. In valve construction in which the valve moves to and from its seat in constantly-parallel planes, the combination of the body having inlet and outlet openings and an interposed seat-opening, a reversible ring-seat fit ted to said last-named opening, an arm on each side of the valve-passage bearing upon said ring-seat, a ring connecting the upper ends of said arm and engaged by the cap of the valve, and means for holding said ring and arms from turning, and the valve which engages with the ring-seat, substantially as described.

3. In valve construction in which the valve moves to and from its seat in constantly-parallel planes, the combination of the body having inlet and outlet openings and an interposed seat-opening, a ring-seat fitted to said last-named opening, a groove on the upper side of said ringseat, an arm on each side of the valve-passage having itslower end resting in the groove of the ring-seat, a ring connecting the upper end of said arm and engaged by the cap of the valve, means for holding said ring-seat and arm from turning, and

the valve which engages the ring-seat, substantially as described.

4. In valve construction in which the valve moves to and from its seat in constantly-parallel planes, the combination of the body having inlet and outlet openings and an interposed seat-opening, a ring-seat fitted to said last-named opening, an arm on each side of the valve-passage bearing upon said ringseat, a ring connecting the upper ends of said arms and engaged by the cap of the valve, a groove in the neck of the valve, a projection upon the ring-seat holder fitted into said groove to hold the ring and arms from turning, and the valve which engages the ringseat, substantially as described.

5. In valve construction in which the valve moves to and from its seat in constantly-parallel planes, the combination of the body having inlet and outlet openings and an interposed seat-opening, a ring-seat fitted to said last-named opening, an arm on each side of the valve-passage bearing upon said ringseat, a ring connecting the upper end of said arms and swiveled to the cap of the valve, means for holding said ring and arms from turning, and the valve which engages with the ring-seat, substantially as described.

6. In valve construction of the character described, and as a new article of manufacture, the ring-seat holder composed of the ring 2' with pendent arms 7' and lugs 70 projecting from the exterior of the ring, substantially as described.

7. In valve construction in which the valve moves to and from its seat in constantly-parallel planes, the combination of the body having inlet and outlet openings and an interposed seat-opening, a ring-seat fitted to said last-named opening, an arm on each side of the valve-passage bearing upon said ringseat, a split ring connecting the upper ends of said arms and engaged by the cap of the valve, said split ring serving by its elasticity to hold itself and said arms from turning, and the valve which engages with the ring-seat, substantially as described.

8. In valve construction in which the valve moves to and from its seat in constantly-parallel planes, the combination of the body having inlet and outlet openings and an interposed seat-opening, a ring-seat fitted to said last-named opening, an arm on each side of the valve-passage bearing upon said ringseat, a split ring connecting the upper ends of said arms and engaged by the cap of the valve, means for holding said ring and arms from turning, and the valve which engages with the rin g-seat, substantially as described.
